The invention relates to a control method and system for a secondary starting switch, and relates to the technical field of engines. The method comprises the following steps of covering the secondarystarting switch with a protective cover, wherein an opening-closing mechanism is arranged on the protective cover, and used for opening and closing the protective cover; when the opening and closing mechanism opens the protective cover, acquiring the gear of a gearbox, and judging whether the gear is a neutral gear or not; if the gear is the neutral gear, starting the secondary starting switch; otherwise, controlling the secondary starting switch to fail. The secondary starting switch cover is covered with the protective cover, so that flameout of a vehicle caused by manual starting of the secondary starting switch can be prevented when the vehicle runs at a low speed. When maintenance personnel performs vehicle inspection and maintenance, the secondary starting switch can only be switchedon when a shifting mechanism is in a neutral state, so that the vehicle is prevented from moving in a non-neutral state; the safety of detection personnel is ensured; and severe consequences and safety accidents during inspection of an engine system and cab lifting mechanism are avoided.
Description
Technical field [0001] The present application relates to the field of engine technology, and in particular, to a control method and system of a sub-start switch. Background technique [0002] The sub-start switch on the truck is often used frequently, using the secondary start switch to ensure that the gearbox is hung into the neutral, otherwise the truck will move, because the vehicle does not have a driver to manipulate, will cause serious consequences. At this time, if the vehicle is performing other detection operations, people will be critical. [0003] In the relevant techniques, the application number is disclosed in China Patent Publication No. 201610350351.4 discloses an automobile engine sub-start switch control box, which integrates a waterproof connector and a mounting bracket, an integrated sub-start switch on the mounting bracket. The purpose of improving the protection level, improving the volume of reliability and reduced the bracket volume. [0004] However, whe...
